Isoleucine, one of the essential amino acids essential for our bodies but cannot be synthesized internally, must be acquired through dietary sources or supplements. It plays a pivotal role in collagen synthesis, crucial for preserving skin elasticity and firmness. Additionally, isoleucine facilitates the healing of skin wounds by promoting the formation of new blood vessels, accelerating tissue regeneration, and boosting collagen production at the wound site. Acting as an antioxidant, isoleucine counters free radicals, safeguarding skin cells from harm and contributing to overall skin health and radiance.
